Bernard A. Harris, MD, of Houston, the veteran of two space shuttle missions and the first African-American to walk in space, visited NJIT today, first teaching in the morning, then speaking to youngsters participating in the ExxonMobil Bernard Harris Summer Science Camp. NJIT once again served as one of 30 locations throughout the nation and the only NJ venue for the two-week residential camp, which offers middle-school students a first-hand experience with experiments, role models and innovative programs to stimulate their interest in engineering and science as a potential career path.
